IMPROVEMENT IN RAILRoAn-AxLE.

The ,Schedule referred to in these Letters Patent and making p rt O thea- To all whom it may concern: V

Be it known that I, Gnonen H. H AGLAM), of Port Jervis, in the county ofOrange, andState of New York, have invented anew and useful Improvementin Railroad-Axles, of which the following is a full, clear, and exactdescription, reference being hadto the accompanying drawing, formingpart of this specification, and in whioh- Figure 1 represents alongitudinal view of the'end portion of a railroad-axle, col'lstructedin accordance with my improvement, and

Figure 2 a longitudinal section of the same, with the turing anew axle,or of repairing an old or worn one, in

drawing out or otherwise reducing the ends of the axle, made, as usual,of wrought-iron, and then bringing said ends to a welding or othersuitable heat, and casting on or over each of them a steel coat or outercovering,

by running the molten metal into a mould, surr0unding the end of theaxle, to an extent and of a size. and shape necessary to form thejournal, the steel becoming, by a state of'fusion, incorporated with orwelded into or on to the drawn or reduced heated end of the wroughtironaxle, after which the axle and journal are hammered into proper shape,and thejournal finished as required; and by extending thesteel coat thusapplied to either end of a wrought-iron axle, beyond the journal, and soas to embrace a portion of the body of the axle, and to enter or bereceived within, say, one-half the hubof the wheel, thereby giving ampleprotection to that portion of the axle most liable to break.

Referring to the accompanying drawing, A represents a wrought-ironrailroad-axle, in part, with its e1 (t drawn or reduced, as shown infig.2. The old or m axle, thus formed, at its opposite ends, has such portioafterwards brought to a red or other suitable heat, sa successively, asit is preferable to cast the steel 00 first on the one end of the axleand then on the 0th byplacing the axle in a verticalposition, and runni]the molten steel in from above, reversing the ends the axle uppermostfor the pin-pose. The steel is r1 into a mould, surrounding the heatedend of the axl to giver proper size and shape to the coat, which thbecomes incorporatedwith the wrought-iron portio and the whole isatterwards hammered to give prop solidity and shape to axle and journal,and finished As represented in the drawing, it is preferred make thedrawn or reduced end a longer than t] journal I), so that the cast-steelcoat B-may be e. tended to enter wholly or in part the hub O of t]wheel, say, for half its width, 'or thereabouts.

A wrought-iron axle, thus provided with steel jou nals, will ofcourse-be much more durable than witho the steel wearing-surface,without proportionably ad ing to the cost of its construction.

I do not claim, broadly, uniting steel with iron, I casting the formeron to the latter whilst at a weldin heat, and subsequently rolling orswaging the ma into form; nor do I claim a wrought-iron axle, with steelfacing, produced in like manner, or by conversh of the exterior in acementation-fiunace, when so steel facing extends the entire length ofthe axle shaft; but v What I'do claim as new, and desire to secure '1Letters Patent, i's

A wrought-ir0n axle, constructed with steel journz casings, extendingabout midway into the eye oft] wheel, substantially as and for thepurposes specific GEOR. H. HOAGLAND.
